Prior to 8.36.1, Marten's full-text search APIs interpolated the user-supplied regConfig parameter directly into the generated SQL without parameterization or validation, making every code path that exposes regConfig to untrusted input a SQL injection sink. This vulnerability is fixed in 8.36.1.","published":"2026-05-28T20:20:11.377Z","modified":"2026-08-07T11:31:04.292676874Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00375,"percentile":0.30217,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"Marten","fixedVersion":"8.37.0"}],"fix":{"url":"https://github.com/JasperFx/marten/commit/626249656829860b9c55895b5b6046b61a2a695f","label":"JasperFx/marten@6262496"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45288.json"},{"type":"ADVISORY","url":"https://github.com/JasperFx/marten/security/advisories/GHSA-vmw2-qwm8-x84c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45288"},{"type":"FIX","url":"https://github.com/JasperFx/marten/commit/626249656829860b9c55895b5b6046b61a2a695f"},{"type":"FIX","url":"https://github.com/JasperFx/marten/pull/4343"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:04.292676874Z"}}
